Hello,

I need to buy push-on lens caps for a 210mm Caltar-II-N (Sironar-N) which I have bought, but it will take about 2 weeks to get it. In the meantime, I could already order the caps if somebody could indicate the diameters needed.

I think that the front cap has to be 70mm and the rear one is 60mm, but as I am not sure, I would be grateful if somebody who owns this lens could confirm.

Thank you

Aender
